Item Description
Allow   pulldown removal 
when opening 24p DV
Select this check box if you want to  remove pulldown  when you open 
24 fps progressive-scan DV video files.
When the check box is cleared,  24p video is read as 29.97 fps 
interlaced video (60i).
AAF  Export - Use frame 
unit for audio
Select  this check box if you want to use frame units for audio tracks 
when you  export your project as an AAF file. When the check box is 
cleared, audio  will be exported as sample units.
Selecting the check box will  improve compatibility with other 
applications for project interchange:  some applications will not 
import your project correctly when frame units  are used for video and 
sample units are used for audio. 
Clear the check box only if  your project contains audio only or if you 
know the application that will  import your AAF file supports frame 
units for video and sample units for  audio. 
This setting has no effect when you export your project  as an 
AAF and choose Avid Legacy AAF  File from the Save as Type  
drop-down list. Avid legacy AAF files are always exported using 
frame  units for audio.
For more information, see "Importing and Exporting AAF Files" on 
page 73.
AAF  Export - Use clip-
based audio envelope
Select  this check box if you want to combine track and event gain 
envelopes and  save them as clip-based gain envelopes when 
exporting  AAF files. 
When the check box is cleared,  track envelopes are saved as track 
envelopes, and event envelopes are  saved as clip envelopes.
For more information, see "Importing and Exporting AAF Files" on 
page 73.
